WILLIAM L. ROORBAOH, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TO S. TWITGHELL & BROTHER, OF SAME PLACE.

BOTTLE-FORMING TOOL.

SPECIFICATION forming part of Letters Patent No. 316,832, dated April 28, 1885.

Applicaticn filed November 24. 1883. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM L. ROORBAOH, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Bottle-Forming Tools, which improvement is fully set forth in the following specification and accompanying drawings, in which-- Figurel is a side elevation of a bottle-forming tool embodying my invention. Fig. 2 is a central longitudinal section thereof. Fig. 3 is a side elevation at a right angle to Fig. l, a portion of the top thereof being broken away. Fig. 4 is a horizontal section in line 00 m, Fig. 1.

Similar letters of reference indicate corresponding parts in the several figures. My invention consists in providing a bottleforming tool with means for forming on the inner face of the mouth of a bottle a groove which is adapted to receive a packing or seat for an internal stopper.

It further consists of means for indicating that the tool is fully closed.

Referring to the drawings, A represents the jaws, and B the plug, of a tool adapted forshaping or forming the mouth and neck of a glass bottle, which, excepting as far as my invention is concerned, is of usual construction.

In the plug B, near the base thereof, is a recess, a, in which are fitted bits 0 O, which in their normal position are flush with the plug, the same being connected with springarms D D, attached to the end of the tool opposite to the plug, said arms being interposed between the handle portions of the jaws, and spread or bowing, so as to force the bits inwardly against or toward each other. The portions of the arms D are passed freely through the bar E,which supports the plug B, and each arm has firmly connected with it a screw bolt or pin, F, the latter also passing freely through the other arm, as at b, the heads of the bolts bearing against the outside of the handle por- 5 tion of the tool, on opposite sides thereof.

In order to adjust the throw of the springarms D, and consequently of the bits 0, I apply to the bolts F, between said arms and the handle portion of the tool or other abutments,

5o nuts G, which are securely held by jam-nuts,

and in order to insure a firm connection of the ends of the bolts F with the arms D, I employ jam'nuts H; but other devices may be employed for said purpose.

When the tool is grasped and the plug inserted in the mouth of the bottle, the latter being properly held, the handles are pressed together, thus advancing the jaws A toward the neck of the bottle, and when the handles reach the nuts G and their inward motion is continued the spring-arms D are separated or forced in opposite directions, thus causing the bits to emerge from the recess a and project beyond the wall of the plug B, as most clearly shown in Fig. 2. The tool is now rotated, and 6 the bits form on the inner face of the neck of the bottle a groove corresponding to said bits, the jaws and plug performing their usual operations. When the required groove is fully formed, the handles are permitted to expand 0 and the parts assume their normal positions, the bits re-entering the plug and thejaws separating, whereby the withdrawal of the plug from the bottle, or vice versa, may be readily accomplished, the bits presenting no obstacle 7 5 thereto.

On the sides of the bar E, near the ends thereof, are shoulders J, which, when the jaws are closed, abut against the jaws A. Consequently when the tool is in operation the workman observes said shoulders J, and if they are in contact with the jaws it is evident that the tool is fully closed and the bits are properly projected from the plug to form the groovein the mouth of the bottle of the proper depth.

When the tool opens or assumes its normal position, the springs or spring-arms D cause the return of the bits. The handles then press against the heads of the bolts or pins F, moving the lattcr to full extent and causing the proper centering of the bits in the plug. In lieu of the heads of the bolts or pins, I may form slots therein, the same being at the outer ends,and have passed through them pins which are attached to the handles, prod ucing the same 5 results as the heads.

Having thus described my invention, what I claim as new, and desireto secure by Letters Patent, is

1. In a bottle-forming tool, the spring-jaws 10o spring-arms D D, plug B, bits 0, screws F,

adjusting-nutsG and H, and a bar, E, having shoulders J said bar guiding the jaws A A and limiting the closing motion thereof, substantially as and for the purpose set forth.

4. In a bottleforming tool of the order stated, the bolt or pin F, provided with means for adjusting the throw of the bit 0, substantially as and for the purpose set forth.

5. The jaws A, plug B, and bit 0, in combination with the bar E, formed with shoulders J, substantially as and for the purpose set forth.
